Unreal Engine Issues and Bug Tracker (UE-57452)

Description
Using AActor::Rename to change the Outer of an actor to a SubLevel will cause the editor to crash when the AActor is shown in the World Outliner.
Regression?: Yes
This does not happen in 4.18 but the rename doesn't seem to occur either
Steps to Reproduce
Download the attached project
Open the project
Press Play
Press Shift+F1 to regain control of the cursor
Scroll down in the World Outliner to find MyActor1
Result: The editor crashes while scrolling through the World Outliner
Expected: You find the actor in the World Outliner
Callstack
Access violation - code c0000005 (first/second chance not available)
